Oracle Video Server(TM) Installation Guide: Sun SPARC Solaris Release 2.1.7.3 A48486-2 |
|
This chapter lists information which must be obtained prior to installing the Oracle Video Server (OVS) software.
Topics covered in this chapter are:
Before you begin the installation of the OVS, obtain the following information and record it for use during the installation procedure:
To install the OVS, you will need to perform administrative tasks as the user root. Ensure that you have the root password prior to beginning any installation tasks.
The OVS must be run under a user account with read, write, and execute permissions, and a group with read and execute permissions. Decide the user ID and group names under which you wish to operate the OVS.
You will need to install the OVS software in a directory location with 100 MB of free space.
From your system or network administrator, obtain the IP address of the network interface card used by the OVS, or refer to your server platform's documentation on how to obtain the IP address.
Select an available UDP port number between 1024 and 65535. The Oracle Installer uses the default value of 5000.
You must obtain the names of the disk drives to be used by the Oracle Media Data Store (MDS) before beginning the installation. The Oracle Installer will ask you to list the disk name of the first disk being used by the MDS volume. The notation for disk names is as follows:
/dev/rdsk/c
nt
nd0s
n
where:
If using SCSI bus 0 with three disks numbered 0-3, using partition 6, the disk names are:
/dev/rdsk/c0t0d0s6
/dev/rdsk/c0t1d0s6
/dev/rdsk/c0t2d0s6
/dev/rdsk/c0t3d0s6
For more information on disk names, refer to your server platform's administration documentation.
You must know the number of SCSI controllers being used by the Oracle Media Data Store.
The OVS supports the use of a spare disk, which can be used if a single disk fails within an MDS volume. If the MDS volume is RAID protected, the data from a failed hard disk can be reconstructed to the spare. This ensures that your MDS volume can remain operational should another hard disk fail before you can replace the failed disk. One spare disk can be used per MDS volume.
Spare disks are an optional feature of the OVS, but a recommended feature if you wish to maintain high availability of data.
The number of video streams that can be reliably provided by the video pump is dependent upon a number of system configuration variables. Video stream bitrate, server processing power, available memory, disk I/O, network, and network interface bandwidth will all influence the performance of your system.
During installation of the OVS you will be asked to provide a value for the maximum number of video streams you want to be supported per video pump. Select a number that is the maximum concurrent number of video streams that you will require. The number you specify will influence the amount of server memory that is allocated for stream delivery. Choose this number judiciously; setting a number higher than needed may allocate system resources unnecessarily.
Note that setting a particular value for this parameter will not in itself ensure support for this number of streams. As indicated above, you must ensure that the particular stream bitrate, server processing power, available memory, disk
I/O, network, and network interface bandwidth will all enable support of the number of video streams required.
At a later time, if additional video streams are required, you may increase the number of video streams per video pump. Alternatively, you can start one instance of the video pump for each processor your server contains (minus one to run the OVS and the server operating system). For more information on either of these steps, refer to The Video Pump in the "Oracle Video Server Components Reference" chapter of the Oracle Video Server Administrator's Guide. For system planning information refer to the "System Planning for the Oracle Video Server" chapter of the Oracle Video Server Administrator's Guide.
You must know if the server being used to run the OVS is a uni-processor or symmetric multi-processor (SMP) server. If you are using an SMP server, you will need to assign video pumps to one or more processors as a post-installation task.
